Improving the Quality of Building Materials –
International Norms for Tile Adhesives & Grouts
INTRODUCTION
Tile adhesives are used to install tiles in residential and
commercial buildings on floors or on walls. Depending on the
local construction technology, regional needs and building
traditions, the choice of raw material, critical performance
criteria as well as norms and regulations for testing adhesives
can differ from country to country.
Test standards as well as high quality additives substantially
contribute to long-term performance extending the durability
of the whole construction – an important aspect with regard to
the sustainability of buildings as well as to their maintenance
costs. The standards define that an adhesive passes certain
performance tests before it may be accredited with a
classification. They also reflect increasing performance needs,
such as fast-setting resulting, for instance, from higher time
pressure during application or stronger adhesion, as a result of
large-size tiles being used more often. They also allow the enduser to compare products and their performance by defining
precise analytical measurements and procedures for testing.

Additives have a strong impact on many of the performance
criteria which are part of the required testing. Methyl Cellulose
(MC), such as WALOCEL™ and METHOCEL™, is used in tile
adhesives and grouts as a thickening and water retention
additive. Redispersible polymer powders (RDP), DOW™ Latex
Powders (DLP), are used to improve deformability and high
bonding strength on different substrates also under critical
conditions. Both types of additives control fresh mortar
properties, rheology and application performance as well as
the final strengths of tile adhesives and grouts respectively.
TECHLINE9 - 1
DEFINING QUALITY AND RAISING
DURABILITY – NORMS & STANDARDS
In Europe, the standards EN 12004 [e] and EN 12002 [f] define
the various performance criteria for adhesives for tiles.
The norm EN 12004 [e] specifies the values for performance
requirements for all ceramic tile adhesives [cementitious (C),
dispersion (D) and reaction resin (R) adhesives]. Each type
can be divided into two classes with either normal (type 1) or
improved (type 2) properties. Norm DIN EN 12002 [f] defines
the deformability of cementitious mortars and grouts.
Apart from defining technical requirements the CE mark is
an important label affixed by manufacturers to confirm the
conformity of their products with the relevant European
standards. It is the manufacturer's declaration that a product
complies with the essential requirements of the relevant
European health, safety and environmental protection
legislation, in practice by many of the Product Directives.
CE marking has been mandatory for thin-bed tile adhesives
since 2004 and ensures, on one hand, the free movement
of the product within the EFTA & European Union indicating
to governmental officials that the product may be legally
placed on the market in their country. On the other hand, it
permits customs and authorities the withdrawal of any nonconforming product. The minimum requirement for CE marking
is a class C1 rating according to DIN EN 12004 [e].
Based on the EN standards the global standard ISO 13007 was
implemented in 2005. The basic requirements were adopted
from the European norms EN 12004 [e] and EN 12002 [f].
The long term goal of the International Standards Organization
is the establishment of homogenized terminology and
technical requirements which are adhered to by adhesive
manufacturers around the world. ISO 13007 consists of four
parts covering specifications (part 1) and test methods for
adhesives (part 2) as well as for grouts (parts 3 and 4).
Cementitious tile adhesives (C) are rated and classified
in terms of tensile adhesion strength and deformability.
Tensile adhesion strength is tested for four different storage
conditions. Depending on the requirements cementitious tile
adhesives are either classified as C1 to achieve minimum
values of 0.5 N / mm² or as C2 with adhesion strengths of at
least 1.0 N / mm² respectively. This classification also gives
the following additional characteristics:
− F = mortar with accelerated setting
− T = mortar with reduced slip
− E = mortar with extended open time
− S = deformable (S1) or highly deformable adhesive (S2)

The introduction of EN 12004 [e] and EN 12002 [f] as well as
ISO 13007 respectively, has led to quality categories for
cement based tile adhesives of classes C1 and C2 for slip
resistance, adhesion strength, open time and transverse
deformation (classes S1 and S2). The technical requirements
for cementitious tile adhesives specified according to
ISO 13007-1 [a] are outlined in table 1.
The trend for increased fast-setting qualities due to earlier
traffic load has been adopted by EN 12004 [e] and ISO 13007.
According to both norms the requirement for the minimum
adhesion strength for fast-setting tile adhesives has been
changed from 0.5 N / mm² after 24 hours to 0.5 N / mm² after
6 hours.
Today the thin-bed technique has replaced the thick-bed
mortar method in most industrialized countries.
This technology is attractive due to savings made as less
material is used and due to an essentially better adhesion of
the tile on the wall. With this thin-bed technique using
specially designed pre-packed dry-mix adhesive mortars,
technical demands on modern building industry using different
types of substrates and covering materials under varying
climatic conditions can be satisfied.
Depending on the different demands there is now a broad
range of ceramic-tile adhesives available, which can be used
The overall characteristics of a thin-bed adhesive can only be
achieved by pre-packed polymer-modified cementitious dry
mix mortars containing cellulose ethers as a water retention
aid and a rheological modifier as well as redispersible
powders as a polymer binding agent. Some typical tile
adhesive formulations are given in table 2.
The appropriate choice of tile adhesive is governed by various
criteria. Apart from varying conditions on the jobsite (humidity,
heat, frost-thaw, air circulation etc.) key parameters include
the nature of the substrate and the type of covering material
and its characteristics (e. g. pattern, smoothness of the
surface, mechanical strength, water absorption, shape and
color etc.). Most popular are ceramic tiles like earthenware,
stoneware, fully vitrified stoneware and Terracotta. But
bonded tiles e. g. glass tiles, natural and mosaic tiles are also
frequently used.

According to current international norms (ISO 13006 [d]),
ceramic tiles are classified into nine groups based on two
features: the level of water absorption and the shaping
method. This simple classification covers the extremely wide
range of existing products in the market. The chosen features
are also significant factors in defining the performance
specifications for different products.

Table 3: Technical Classification of Tiles according to ISO 13007-2 [c]
There is an ongoing trend in the market for large and fullyvitrified ceramic tiles. They enjoy great popularity due to their
superior resistance to a variety of environmental stresses.
Thanks to their small pore sizes, a low absorption level of less
than 0.5 % and a dense, smooth surface finish (e. g. glazed tiles),
they are capable of withstanding the high levels of chemical
(e. g. improved stain resistance), thermal (e. g. reduced risk
of frost damage) and mechanical surface stress (e. g. high
scratch and abrasion resistance). The requirements for tiles
specified according to EN 12004 [e] (and especially ISO 13007)
are already reflecting this trend.
Tiles with very low water absorption values and with a more
glazed and smooth surface lead to lower adhesion strength,
and raise the requirements for the modified mortar.
Norm ISO 13007 reflects this trend with specifications for
water absorption rates of fully vitrified unglazed tiles not
exceeding 0.5 %, to be used for the tensile adhesion strength
tests.
To meet these demands special methyl cellulose ethers and
redispersible powders are used as additives in tile adhesives
to avoid any application failure on the one hand and to achieve
sufficient tensile adhesion strengths also under critical
conditions (e. g. heat, frost-thaw) as well as long open times
on the other. Apart from these basic requirements further
additional properties like easy workability, less stickiness
on the trowel, reduced slip, long adjustability and sufficient
deformability are some further features the applicator may be
looking for.
Adhesive strength is the tensile strength of the total system
consisting of tile, mortar and substrate. The cementitious tile
adhesive between these two materials provides the adhesion
strength, which is measured by a pull-off test according to
EN 1348 / ISO 13007-2 [c]. The force in Newton (N) at which
the system fails is divided by the cross-sectional area (mm2)
of the tile resulting in the adhesive strength (N / mm2).
The system can fail at the interfaces between mortar and
substrate, at the interface of the mortar and the tile (adhesion
failure), or within the mortar layer itself (cohesion failure).
Generally, the system fails along or near the mortar-tile
interface.
However, due to the low water absorption and the very
smooth surface finish of vitrified tiles, it is very difficult to
fix these tiles to the substrate (mostly concrete or wood).
Therefore, taking the trend for more critical substrates into
account, the use of organic binders, e. g. dispersions or
redispersible powders, DOW™ Latex Powders (DLP), in the
formulation is a must to improve the mechanical properties.

Apart from high adhesion strength following different storage
conditions, the open time is an important factor and is defined
in the test standard EN 1346 / ISO 13007-1 [a] as the maximum
time interval after application at which tiles can be embedded
in the applied adhesive and meet the specified tensile
adhesion strength requirement. The maximum open time of a
mortar refers to the latest time a tile can be laid in without a
major loss in final adhesion strength. After 28 days the pull off
strength is determined with a minimum requirement of
0.5 N / mm² after a minimum of 20 minutes embedding time for
standard adhesives; at least 0.5 N / mm² after a minimum of
10 minutes embedding time for fast-setting mortars and at
least 0.5 N / mm² after a minimum of 30 minutes embedding
time for high quality tile adhesives.
However, extended open times for mortars are highly
desirable when installing tiles in drier climate zones, in
exterior applications where windy conditions often prevail and
when installing especially large-sized tiles that require more
time for adjusting grout lines. In addition, the more porous
the substrate and the more absorptive the tile is, the less
time the installer has available to lay tiles. While in a typical
mortar this may result in loss of bonding, a tile adhesive with
extended open-time properties will give the installer the
necessary time to achieve optimal adhesion. According to
the EN- and ISO-standard the minimum requirement for the
extended open time is raised from 0.5 N / mm² after 20 min
for a standard open time to 30 minutes for the adhesive with
extended open time.
The transverse deformation has been implemented as
EN 12002 [f] first and has been adopted by the international
norm ISO 13007. The intention to set up requirements for
the deformation of tile adhesives reflects the fact that tile
adhesives are submitted to different stresses as a result
of changing mechanical or climate conditions (floor heating
system, outdoor exposure – heat, frost-thaw – etc.) which the
adhesive has to endure. Taking this into consideration, the test
determines the deformability of a mortar which is the capacity
of the hardened adhesive to be deformed by stresses between
the tile and the fixing surface without damaging the surface.
The deformation is recorded as deflection at the centre when
a layer of the hardened adhesive is subjected to a three-point
loading. The tile adhesives are categorized, according to
EN 12002 [f] / ISO 13007-1 [a], into two classes and are
designated as either deformable adhesives of class S1
with a deformation of at least 2.5 mm but below 5 mm or as
highly deformable adhesives of class S2 with a transverse
deformation of at least 5 mm.

Determination of Deformation
The deformation of mortars is determined acc. to a
three-point flexural strength test with defined specimens

≥ 2.5 mm and < 5 mm
S 2: deformation of highly deformable mortars:

Without considering the requirements according to
EN 12004 [e] / ISO 13007, there are different options to
conduct the test by either changing the cement ratio while
keeping the addition rate of the redispersible powder
unaltered (Figure 2) or vice versa (Figure 3).

Polymer Powder
In both cases the ratio of cement to the polymer binder is
being altered to meet the requirements of the norm in terms of
flexibility.
DOW™ Latex Powders (DLP) offer a number of benefits to
the wet and dry-mortar properties of tile adhesives. When
the dry-mix mortar is mixed with the required amount of
water, the DLP polymer powder re-disperses completely in the
aqueous phase. This is the precondition for a homogeneous
film formation of the polymer during the subsequent setting
of the mortar. In addition to the cement matrix the polymer
matrix contributes to the bonding and compressive strength of
the mortar.
Therefore, cementitious grouts must have good adhesion to
the edges of the tiles, low shrinkage, sufficient flexibility to
bear mechanical damage or thermal stress, high abrasion
resistance and low water absorption. The specifications for
grouts are outlined in the international standard ISO 13007-3 [b].
DLP redispersible polymer powders are required in those
tile adhesive applications where – especially on different
substrates – adhesion strength needs to be improved or
special technical requirements (e. g. heat conditioning) have
to be fulfilled. They also impart high flexibility or impact
resistance and improved abrasion resistance once the mortar
has hardened. Additionally, some tile adhesive formulations
contain special performance DLP polymer powders which
improve either the water repellency characteristics or the free
flowing abilities of the mortar.
Tile grouts are used to fill the joints between tiles or natural
stones either on walls or on floors. In combination with the
tiles they must provide not only an optically attractive surface
but must also perform physical functions.

Cementitious tile grout formulations are generally based
on white cement and calcium carbonate as filler. To ensure
fast setting accelerators or alumina cement are being used.
The addition rate of WALOCEL™ and METHOCEL™ Cellulose

and consistency as well as the water retention and final
mechanical strength.
Dispersion bound adhesives are commonly known as organic
adhesives or mastics and are mainly used for applying
wall tiles. They have become increasingly popular, serving
as a prime adhesive choice for a variety of tile and stone
installations because they are easy-to-use as they don’t
require any mixing.

ISO 13007-1 [a] / EN 12004 [e] classifies dispersion bound
adhesives as D1 (normal adhesive characteristics) or D2
(improved adhesive characteristics with resistance to water)
according to their shear adhesion strength. Dispersion
adhesives are most often used for interior wall installations
involving larger-sized or impervious tiles respectively.
Dispersion adhesives meeting D1 classification standards are
appropriate for interior installation such as commercial and
residential walls, but under dry conditions only. Adhesives
classified as D2 can be used in interior installation with
intermittent exposure to water, such as bathrooms, showers
and kitchens.

Dispersion adhesives exhibiting a minimum shear strength of
1 N / mm2 after dry and heat storage receive a D1 rating.
The D2 rating additionally requires a minimum shear strength
of 0.5 N / mm2 after water storage. Requirements for slip
resistance and extended open time are optional. Due to their
formulation, dispersion based adhesives and reaction resin
adhesives are classified according to their shear strength
values.
8 - TECHLINE9
The addition rate of WALOCEL™ and METHOCEL™ Cellulose
Ether is required to provide the necessary rheology, water
retention and – if required – slip resistance and open time.
Especially those types with delayed solubility characteristics
are recommended to impart the appropriate incorporation.
Increasing the pH to 9 dissolves the cellulose ether
immediately and improves standing strength, open time,
adjustability time, slip resistance and adhesion strength.
However, compared to cementitious tile adhesives the water
resistance of dispersion bound tile adhesives is limited.
